BOILER AND STEAMER.

Specification of Letters Patent No. 25,442, dated September 13, 1859.

To all whom 'it may concern:

Be it known that I, DANIEL R. PRINDLE, of Bethany, in the county of Genesee and State of New York, have invented certain new and useful Improvements in Agricultural Boilers or Steaming Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being hadV to the accompanying drawings, making a part of this specification, in which- Figure 1, represents an elevation of the apparatus; Fig. 2, represents a central vertical section through the same and Fig. 3, represents, on an enlarged scale, the flanges of the upper and lower sections, and the mode of uniting them.

Similar letters of reference, where they occur in the several figures denote like parts of the ap aratus in all of them.

The object of my invention is to make a cheap and efficient portable boiler, or steaming apparatus, for agricultural purposesone that can be easily managed by a farmer, and applicable to all his wants, and which can be transported from place to place where it may be required. And the nature of my invention consists in combining with a cylindrical re-box, a spherical or globular boiler in two sections that may be united or separated at pleasurethe boiler resting upon the fire-box, so that it may be turned around at any time, to bring any of its pipes or tubes in such position, or over any vessel or receptacle into which the stream is to be taken, as will be most convenient. And, my invention further consists in the manner of constructing the sections of the boiler, so that they may be united or separated expe ditiously; and so that also the packing between the sections may be protected from injury by the fire in the furnace or fire-box.

To enable others skilled in the art to make and use my'invention, I will proceed to describe the same with reference to the drawings.

A, represents a caldron, of hemispherical form, and having around its edge a lipped flange e, which supports it upon the firebox. B, is a cover which is also of a hemispherical form, and which has a lipped or both a horizontal and a vertical flange around its rim that forms, (when said cover is placed upon the caldron or lower section) a trough F, Fig. 2, that will hold water. The upper section B, is united to the lower section A, when they are to be used together, as follows: In the vertical flange or lip of either the upper or lower section there are formed inclined planes or wedge acting notches (any suitable number) as seen at Z), Fig. 3. But before the two sections are placed together, a packing, of any of the well known flexible kinds, is placed between the flanges of the two sections. This being done and the sections laid together, clamps 0, o, 0, having inwardly turned hooks z', z', (Fig. 3,) on their extremities, are slipped on at say-the point b, Fig. 3, and driven toward c, which draws the flanges of the two sections t-ight up against the packing, and thus renders the joint between them steam tight. The uniting of the t-wo sections by screw-bolts passing through their flanges, is not only inconvenient, but does not make a steam tight connection, in the hands, at least, of farmers, who have not the skill that steam engineers have in packing steam joints, and steam will leak through the bolt holes, unless skillfully packed.

The fire-box C, is a simple cylinder of sheet or other metal, open at both ends. It is furnished with a door Pmremovable bars N, to serve asa grate-and handles M, for conveniently moving it from place to place, as also, a smoke flue K.

rIhe dome, or upper section B, is furnished with a supply pipe that has a funnel H, upon its outer end, and a stop cock E, to open or close it; it has also a try cock G a steam pipe D, (generally flexible,) for conveying steam to any desired point; and handles L, so that the boiler may be turned around on the fire box to any convenient position to bring the pipes where they may be especially wanted in using the apparatus.

From the funnel I-I, there extends a pipe I, for conveying water from the funnel to the trough F, formed by the flanges of the upper section B. The object in flowing the water into the trough is to protect the packing between the flanges from being burned out as it would otherwise be, by the fire in the fire-box. The fire-box may also be turned, to make its flue suit any chimney, when the apparatus is used in the housewhile, at the same time, the boiler may be turned to connect with any reservoir, cistern, vat, or vessel that may be used in connection with it.

Having thus fully described the nature and object of my invention, I claim- The so turning or forming the flange of the upper section, as that it Will contain Water to prevent the re from burning the packing between the flanges, substantially as described.
